Application filed May 18,

The present invention relates to an improved windshield wiper of theswinging 'or oscillatory type which operates through a limited are onthe outer surface of the glass and which'is operated from suitablemechanical means controlled by appropriatepower means. v

' One improvement .is in the particular construction of the wiperelement, which is of Composite construction, the same embodying a noveldouble shell container for a double edge rubber squeegee, and alsoincluding an apertured fluid conducting tube,-

from the following description and drawings. I

. In the drawings:

Figure 1 is a view showing a portion of the windshield with the improvedstruo' ture mounted thereon.

, Figure 2 is an enlarged side view of the wiper and supporting arm.

1 Figure 3 is an inside elevation of the '35 wiper element, withportions broken away and shown in section.

Figure 4 is an end elevational view. Figure 5 is a cross section takenapproximately upon the plane of the line 5-5 of 4 Figure 2. Y

Figure 6 is a fragmentary perspective view of one end portion of theouter metal shell. 7

In the drawings, the reference character 7 designates generally theimproved wiper which is composed of an outer metal shell 8,aninner/metal shell 9, and an intervening rubber L sheet 10 forming thecustomary squeegee. The shell 8 is of channel shape 5 in cross sectionas is the" shell 9 the latter being somewhat smaller. The edges of therubber heet extend b yond the edges of the .At one end the pipe isprovided with a bead 1927. serm-i'no. 192,301.

shell, and form a double active in both directions.

Attention is directed'to an apertured fluid conducting and-spraying pipe11, located in the channel of the shell 9 having its end portionsconfined between the especially bent retaining bands 11, at the ends'ofthe shell 8.

wiper, which is 12 with which a fluid conducting hose 13 is connected.,Incidentally it' will be noted that by forming the bands 11 at theopposite c ends of the outer shell 8, the ipe isgiven the additionalfunction of-holding the parts of the wiper together, or in assembledrelation. The pipe is preferably surrounded by a snug fitting sleeve 14,composed preferably of felt. v

In practice the supporting and operating arm 15 is provided and isconnected by way of the head 16 to an outstandingflan e 17, on the shell8. The arm 15 is connecte with an operating cylinder 18, controlled fromany suitable source of power. Some of these are operated by exhaust fromthe motor and others from individual electric motors, etc.

As far as the present invention is concerned, it is immaterial how thewipe'r 7 is operated as long as it is permitted-t0 swing back and forthinthe approximate arc indicated in the drawing in Figure 1.

It is our idea to supply a special fluid to the surface of the glass toaid in preventing the accumulation of moisture, snow and ice thereon.Various kinds of fluid are on the market, at this time, for thispurpose, and We therefore provide a cylinder 19 adapted to receive alimited quantity, of the fluid. The cylinder is provided with a valveddischarge 20 with which the afore-' said hose 13 is connected. When thevalve is opened, the fluid gravitates from the cylinder 19 down into theapertured ipe 11, where it is takenup by the a sorbent 'sl eeve. Whenthe sleeve becomes saturated,

Minor changes coming within the field of invention claimed may beresorted to, if desired.

We claim: 7 1 1. As a new product of manufacture, a

wind shield Wiper comprising inner and,

outer channelshaped metal shells, a rubber sheet interposed between saidshells and having itsopposite longitudinal edges extending beyond thecorresponding edges o t saideena 1e tending through said bands forholding said shells and rubber sheet in assembled relation.

As a new product of manufacture, an outer channel shaped shell providedwith reversely bent hands at its opposite ends, a rubber sheet fittedinto said shell. with its edges extending beyond the longitudinal edgesof the shell, an inner channel shaped shell in contact with said rubbersheet, an apertuned pipe having its ends extending through said bandsfor holding said shells and rubber sheets in assembled relation, saidp'ipe'having a hose retaining head at one end and an absorbent sleevesurrounding said pipe. I

In testimony whereof we aflix our sign-atures.
